perf cpumap: Drop in cpu_aggr_map struct

Browse source 
Replace usages of perf_cpu_map with cpu_aggr map in places that are
involved with 'perf stat' aggregation.

This will then later be changed to be a map of cpu_aggr_id rather than
an int so that more data can be stored.

No functional changes.
